IMPROVEMENT IN BINDERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 120,513, dated October31, 1871.

To all whom it may concern:

Be it known that I, HENRY M. HALL, of New York, in the county of NewYork, and in the State of New York, have invented certain new and usefulImprovements in Binding Attachment for Sewing- Machines; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing making a partof this specification, in which Figure 1 is a plan View of the upperside of my device. Fig. 2 is a side elevation of the same. Fig. 3 is across-section of said device on the lines 00 w of Figs. 1 and 2. Fig. 4is a plan view of the upper side of a modification of the binder. Fig. 5is a side elevation of the same, and Fig. 6 is a cross-section on thelines a z of Figs. 4 and 5.

Letters of like name and kind refer to like parts in each of thefigures.

My invention is an improvement in a class of sewing-machine attachmentsemployed for guiding and holding in position. binding-braid while thesame is being attached to or around the edges of fabrics; and itconsists in the device, as a whole, when constructed substantially asand for the purpose hereinafter specified.

In the annexed drawing, Arepresents the frame of the device, constructedof or from a narrow strip of sheet-metal, bent together in a short curveat its longitudinal center, and from thence extending outward inparallel lines to a point near its ends, a, from whence the jaws curvein ward toward each other and then slightly outward, as seen in Figs. 2and 5. Upon each jaw or arm of the frame thus formed is fitted a slide,B, which consists of a piece of sheet-metal, havin g a sufiicient widthso that when placed against the inner face of the arm its edges may beturned upward and inward so as to embrace the edges of the same, andconnect said parts firmly together in a lateral direction, While at thesame time permitting said slide to be moved longitudinally upon saidarm. The inner end I) of each slide is extended forward and inward, andthen horizontally forward, so as to embrace the edges of thebinding-tape. Secured to and extending rearward from the doubled end ofthe frame A is a rod, C, having any desired transverse form, by means ofwhich the device is connected with the clamp or other device used forattaching the same to or upon the supporting plate of the machine. Asthus constructed the braid is doubled together longitudinally and placedwithin the doubled end of the frame A, with the edges of said taperesting within and loosely confined in place and separated by the guidesb, after which the fabric to be bound is passed between the arms or jawsof said frame and between said guides, with its edges inclosed by meansof the doubled braid, in which relative positions the parts are readyfor operation in the ordinary manner. In order that the braid may beheld in position after leaving the binder, and until the instant that itreceives the needle, I employ a guide, I), which extends laterallyoutward in a line with the inner edge of the doubled portion of theframe A, and embraces the doubled edge of said braid. It will be seenthat many modifications can be made in the shape of this guide, one ofwhich is shown in Figs. 1 to 3, and is formed of a strip of springsheet-metal, which is attached to the upper arm of the frame and fromthence extends outward and downward so as to bear slightly upon theupper surfaces of the cloth and braid, while upon its rear side isprovided a lip, d, that extends Vertically downward in rear of andagainst the doubled edge of the braid. Another form of the guide isshown in Figs. 4 and 6, and consists in a lateral prolongation of thedoubled end of the frame so as to form a horizontal semi-circulargroove, 61, within which is contained the doubled edge of the braid.

The device thus constructed is simple and efficient, and can be readilyadapted to use upon any thickness of cloth or any width of braid, whichbraid can be made to overlap equally upon opposite sides of the cloth,or, if desired, may be so applied as to have greater width upon one sidethan upon the other.

Having thus fully set forth the nature and merits of my invention, whatI claim is- As a new article of manufacture, the hereinbefore describedbinder, when constructed substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of September, 1871.
